Regola delli cinque ordini d'architettura
Regola delli cinque ordini d'architettura is an 1736 Italian architectural treatise printed in Bologna by Lelio dalla Volpe, presenting the classical orders of Vignola (1507-1573) with commentary by Gio. Lodovico Quadri for architects and students. Its pictures are precise black-and-white engravings of columns, capitals, entablatures and arches, with modular measurements and construction lines marked in the margins, showing how proportions were set out by a fixed unit, a useful reference for classical ornament, column rhythm and geometric layout.
